What would you weigh on HAT-P-18 b?

Q: What would you weigh on HAT-P-18 b?

HAT-P-18 b has a surface gravity 0.50 times Earth's, so you would weigh about 50% less than you weigh on Earth. A 150 lb person would weigh about 75.5 lb there.

HAT-P-18 b’s surface gravity is 0.50× Earth’s, so you would weigh about 50% less than you weigh on Earth. It is a giant planet with no solid surface, so this is the pull you would feel at its cloud tops. HAT-P-18 b’s gravity is stronger than 2% of the known worlds in gravityfinder (a low bar to miss: most confirmed exoplanets are giants far heavier than Earth).

A 150 lb person, world by world
World	Gravity	You’d weigh
The Moon	0.17×	24.8 lb
Mars	0.38×	56.7 lb
HAT-P-18 b	0.50×	75.5 lb
Earth	1.00×	150 lb
Jupiter	2.53×	379 lb

For scale: the gentlest gravity of any world here is Charon at 0.03×, and the most crushing is Kepler-123 b at 6.40×.
